GUSTAF ARVID ANDERSON, OF WAYNESBORO, PENNSYLVANIA, ASSIGNOR TO THE GIESER MANUFACTURING COMPANY, OF WAYNESBORO, PENNSYLVANIA.

PLOW.

To all whom it may concer-n:

Be it known that I, GUs'rAF Anvin ANDER- sON, a citizen of the United States, residing at Vaynesboro, in-the county of -Franklin and State of Pennsylvania, have invented certain new and useful Improvements in Plows and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to gang plows operated by traction engines; and it consists principally in novel and improved mechanism for connectin(T the plows with the main plow frame and with each other, as hereinafter fully described and claimed.

In the drawings, Figure l is a side view of one of the lows and its draft connections. Fig. 2 is a p an view of the devices shown in Fig. l, showing also the connection of one plow with the next adjacent plow. Fig. B is an end view of the pivoted bracket at the -front end of the draft-bar. Fig. 4 is a detail side view of a modification of the support for the gage wheelf Fig. 5 is a plan view of the same. Fig. 6 is a detail plan view of the jointed brace-bar, showing in section the plow standard and the arms for supporting the gage wheel. Fig. 7 is a plan view of the colter and its su port, from below.

A is a plow o any approved construction, and a is its land-side.

' B is a standard which is secured to the low A, and which is arranged in a substantially vertical position.

C is a draft-bar which is preferably tubular and arranged in an inclined position and pivoted to the upper end portion of the standard B. The draft-bar is provided with a forked bracket c which is pivoted on a pin which projects crosswise through the upper end portion of the standard.

D is a jointed brace-bar arranged under the draft-bar C. The front end of the bracebar is pivotally connected with the front end of the draft-bar, and its rear end is operatively connected with the middle part of the low standard. The said standard, draftar and brace-bar form a triangular frame arranged in a vertical plane and by means of which the plow is drawn along.

A bracket E is secured to the front end of Specification of Letters Patent.

Serial No. 403,353.

the draft-bar C, and the front end of the brace-bar D -is pivoted to this bracket by a pin d.

F are arms which project downwardly from the bracket E, and c is a gage wheel which is journaled on a pin between the said arms.

G is a 'forked draft-bracket provided with a cylindrical projection S which is mounted in the bracket E on the axis of the draft-bar so that it can be adjusted, and g is a draftattachment which is pivoted in the fork of the bracket G on a horizontal pin s so that it can swing up and down.

The improvements herein described are applicable to a gang plow suchas shown in the Patent No. 818,21), dated April 17, 1906.

The draft bracket G permits the draft-bar C, together with the plow and the other parts connected to the said draft-bar, to have a slight pivotal movement upon the axis of the draft-bar. This movement is desirable in order to make the plow A work freely and without any tendency to take more or less land than is desirable. This slight pivotal adjustment of the draft-bar O cants the plowbottom and also moves it laterally towards or away from the open furrow, and thereby causes the plow to take more or less land. This arrangement dispenses with the means for adjusting the line of draft laterally which are commonly used.

The draft bracket G is provided with curved slots 2 which engage with bolts 3 which pass through holes in the bracket E. These slots limit the pivotal movement of the bracket E together with the draft-bar C and the plow, and the bolts 3 afford a means for securing the draft-bar to the draft-bracket after the position of the plow-bottom has been adjusted.

In the modification shown in Figs. 4 and 5, a bracket E is secured to the front end of the draft-bar O, and the brace-bar D is pivoted to lugs on this bracket. A `forked draft bracket G is journaled in the bracket E', and is provided with a pivoted draft attachment q. The gage wheel e is journaled on a pin f between the lower ends of arms F which project downwardly from the forked draft bracket G instead of projecting from the bracket which is secured on the end of the draft-bar O. In this modified form of the device the gage wheel does not move when the draft-bar is moved pivotally on its axis, but the action of the parts is otherwise similar to those hereinbefore described.

H is a standard for supporting the colter I. This standard is provided with clamping devices 7L of approved construction which are adjustable longitudinally upon the draft-bar C so that the standard may be secured in any desired position. The standard H has a vertically arranged pivot 4 at its lower end, and 5 is a block which is mounted on the said pivot. A stop-pin 6 is passed transversely through a hole in the lower part of the pivot, and it engages with a notch 7 in the block, so that the said block is free to oscillate to a limited extent and is retained on its pivot.

Arms 8 are pivoted by a pin or bolt 9 to the block 5 on one side of the pivot 4, and the colter disk I is ournaled on a pin i between the said arms. A curved slot 10 is provided in the block 5, and 11 is a locking-bolt which works in the said slot and engages with holes in the arms 8.

The arms 8 form a support for the colter disk and they are locked to the block by screwing up one or both of the' nuts of the bolts 11 and 9. The lateral position of the colter disk on its pin is adjusted by means of removable washers l2 inserted between the arms and the hub of the disk.

The jointed brace-bar D is arranged to one side ofthe colter standard H. The iront portion of this brace-bar is connected with the front end portion of the draft-bar C. The rear end portion 14 ofthe brace-bar is formed of two plates which straddle the plow standard B. A cam J is pivoted on a pin j between these plates and is provided with a series of holes l5. Plates 16 are secured to the standard, and 17 is a pin which passes through holes in the plates 16 and through any one of the holes 15 according to the position of the cam. Slots 18 are provided in the part 14 so tlliat the pin 17 may be slid into and out of p ace.

The middle portion 20 of the brace-bar is also formed of two plates. The iront end of the part 20 is pivoted to the front portion 2l of the brace-bar by a pin 22, and 23 are links also connected to the pin 22 for the purpose of working and adjusting the jointed portion of the brace-bar. The rear portion of the part 20 is provided with a slidable bolt K which is pivoted to it by a pin 7c. This bolt K is slidable in a hole in a block 24 secured to the rear end portion 14 of the brace-bar.

L is a frangible pin or nail which passes crosswise through holes in the block 24 and bolt K, and which normally connects them together.

The oints ofthe brace-bar are normally arranged in line with each other.

`When the links 23 are raised, and the joints ofthe brace-bar are thereby moved out of line with each other, the plow standard is turned on its pivot b, and the point of the plow is led out of the ground.

The positions of the cam J and the gagewheel determine the depth of the furrow cut by the plow, and the said parts are adjusted from time to time to make the furrows of any required depth.

Then the plow point strikes a solid obstruction which would injure it, the frangible pin L is sheared oil, and the plow is moved pivotally to the rear with respect to the draft-bar, but it is not disconnected from the draft-bar. The plow is dragged along but without doing any work, until replaced in its normal position, and a new pin L is then inserted.

A spacing-block il is pivoted on one end portion of the pivot-pin b at the top of the plow-standard, and the eye n of a spacingarm n is pivoted on the other end portion of the said pin l), as shown in the upper part of Fig. 2.

The plows of the gang-plow are all alike and are arranged in parallel planes. The spacing-arm of one plow is slidable longitudinallyin the spacing-block of the next adjacent plow, so that each plow can move rearwardly about its pivot b when a rangible pin L is sheared through, but all the plows are held in position laterally and are kept parallel-with each other. A stop-pin p is provided in the end portion of the spacingarm n to prevent it from sliding out of engagement with its spacing-block .after a frangible pin has been sheared through.
